First question. The midpoint of SR is...

Blizzard [7]

The formula of a midpoint SR:

$M\left(\dfrac{x_S+x_R}{2},\ \dfrac{y_S+y_R}{2}\right)$

We have

S(4, 1) and M(7, -5)

Substitute:

$\dfrac{4+x_R}{2}=7\qquad|\cdot2\\\\4+x_R=14\qquad|-4\\\\x_R=10\\\\\dfrac{1+y_R}{2}=-5\qquad|\cdot2\\\\1+y_R=-10\qquad|-1\\\\y_R=-11$

<h3>Answer: R(10, -11)</h3>

Each face of a cube has an area of 16 inches squared what is the volume of the cube

lakkis [162]

Answer:

64 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the length of the side )

Given

area = 16, then

s² = 16 ( take the square root of both sides )

s = $\sqrt{16}$ = 4 , thus

V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
